A incidência de altas concentrações de selênio (Se) no solo é relatada em várias partes do mundo. Em regiões do estado de São Paulo se observou deficiência em gramíneas, provavelmente associadas ao solo, que em alguns países é corrigido através de fertilização. O Se é essencial aos animais e sua deficiência implica na ocorrência de doenças e nas plantas superiores sua essencialidade também foi constatada. É relevante a falta de informações sobre o assunto a ser estudado, principalmente em solos tropicais. O objetivo da pesquisa foi à obtenção de informações sobre Se no sistema solo x planta. O

Abstract:
A sodium laser guide star (LGS) adaptive optics (AO) system developed at Stewart Observatory is to be used at the 6.5m MMT. Annual measurements at Kitt Peak show that the mean mesospheric sodium column density varies from ∼2x10⁹cm⁻² (summer) to ∼5x10⁹cm⁻² (winter). The sodium column density also varies by a factor of two during a one hour period. The first simultaneous measurements of sodium LGS brightness, sodium column density and laser power were obtained. The absolute sodium return for a continuous wave circularly polarized beam is 1.2(±0.3)x10⁶ photons s⁻¹m⁻²W⁻¹ for the sodium column dens

Abstract:
Sodium dithionite (Na2S2O4) is a powerful reducing agent. It has therefore been suggested to be used as an additive in kraft pulping to improve the yield. However, sodium dithionite easily decomposes and it is thus important to determine the effect of different conditions. The aim of this thesis has been to investigate the thermal stability of sodium dithionite under anaerobic conditions using ATR-FTIR spectroscopy under different conditions, such as heating temperature, concentration of the solution, heating time and pH. The stability of sodium dithionite was found to decrease with increasing

Two spectral regions of gain exist for a weak probe beam propagating through a medium of two-level-atoms pumped by a strong near-resonance field. Experimentally a cw ring-dye laser is used to explore this gain at the Na D₂ resonance in a vapor. Plane-wave calculations of probe-gain spectra which include the Doppler broadening inherent in a vapor agree well with experimental spectra obtained with a Fabry-Perot interferometer. Such two-beam-coupling gain might have applications as optical pre- or power amplifiers. The gain is also the primary step in four-wave-mixing. Mixing of the pump and side

Une telle réaction chimique ne peut théoriquement pas s’emballer, or les observations démontrent le contraire.

Un mécanisme présenté précédemment propose d’expliquer ces observations par la vaporisation rapide du sodium.

A catalytic route to hydrogen production via thermochemical water splitting is highly desirable because it directly converts thermal energy into stored chemical energy in the form of hydrogen and oxygen. Recently, the Davis group at Caltech reported an innovative low-temperature (max 850C) catalytic cycle for thermochemical water splitting based on sodium and manganese oxides (Xu, Bhawe and Davis, PNAS, 2012). The key steps are thought to be hydrogen evolution from a Na2CO3/MnO mixture, and oxygen evolution by thermal reduction of solids formed by Na+ extraction from NaMnO2. Our work is aimed

Dissociation mechanisms were previously proposed based on MSn experiments, where n>2; however, a dissociation pathway achieved by an MSn experiment, where n>2, may not necessarily be the same pathway achieved in an MS2 experiment.

Sodium borohydride is stable in alkaline solution, however, it hydrolyses and generates hydrogen gas in the presence of suitable catalyst.

The limited surface area of the heterogeneous and therefore, have limited activity because of the surface area.

Abstract:
The field of molecular bioenergetics deals with the energy transduction in biological cells. In this project, respiration and more specifically proton and sodium pumping enzymes and their coupling to electron transfer have been in focus. First we have been interested in the Na+-pumping NADH:quinone reductase from Vibrio cholerae which is the entry site of electrons in the respiratory chain of several pathogens. The role of specific flavin cofactors and amino acids involved in Na+ transfer has been shown in a combined IR spectroscopic and electrochemical approach. The interaction between protei

Abstract:
A ocorrência de monofluoroacetato de sódio (MFA-Na) em plantas foi registrada, pela primeira vez, em Dichapetalum cymosum. Posteriormente, esta substância tóxica foi encontrada em outras espécies de plantas, como Palicourea marcgravii, causadora de morte súbita. Amorimia rigida, que é bastante conhecida e frequente no Nordeste do Brasil, está entre as plantas tóxicas, que também causam morte súbita em bovinos, com quadro clínico semelhante ao decorrente da ingestão de plantas que contém fluoroacetato de sódio e ao apresentado por animais intoxicados experimentalmente com este tóxico.

Abstract:
The principal goal of this Doctorate thesis is to study high frequency vibrations (in the range between Gigahertz and Terahertz) in nanoscopic biological structures such as proteins. In particular, the idea of this thesis is to found, by means of experimental sessions and numerical simulations, natural frequencies of entire proteins or of large portions of that. The mechanical behaviour of proteins is receiving an increasing attention from the scientific community. Recently it has been suggested that mechanical vibrations play a crucial role in controlling structural configuration changes (f

Abstract:
La thèse présente un modèle basé sur la physique pour les cellules sodium-ion de type NVPF/HC. Le modèle tient compte des complexités de la modélisation de ces cellules, notamment à cause de leurs non-linéarités liées au courant, à la température et à l'état de charge (State of charge : SoC). La structure du modèle est un circuit équivalent amélioré par des concepts utilisés dans les modèles à particules uniques (Single particle model : SPM) pour former une structure ECM-SPe, adaptée aux diagnostics de SoC et d'état de santé (State of health : SoH). La structure ECM-SPe sépare les effets de la

Abstract:
The stability of glass is linked to its composition and the atmosphere controls its alteration. The organic pollutants emitted by wooden showcases play a role in the alteration of historic glasses. This study examines the effects of acetic acid, formic acid and formaldehyde on objects from the National Museums of Scotland and on replica glasses aged artificially, all with a soda silicate composition. Composition was determined by electron microprobe and analytical decomposition of the Raman spectra was used to establish correlations between glass structure and composition. This allowed interpr

Abstract:
Phase equilibria and volumetric properties in the system water-sodium chloride-carbon dioxide were determined experimentally for pressures between about 1 to 6 kbar, temperatures of 300° to 800°C, and fluid compositions up to 40 wt% NaCl and 20 mol% carbon dioxide, both relative to water. This was accomplished by using the synthetic fluid inclusion technique in conjunction with conventional microthermometry, a hydrothermal diamond-anvil cell and Raman spectroscopy. At constant salinity, the high-pressure portion of the solvus migrates to higher pressures and temperatures with increasing carbo

Abstract:
Due to the limited resources of lithium, new chemistries based on the abundant and cheap sodium and even zinc have been proposed for the battery market. Prussian Blue Analogues (PBAs) are a class of compounds which have been explored for many different applications because of their intriguing electrochemical and magnetic properties. Manganese and titanium hexacyanoferrate (MnHCF and TiHCF) belong to the class of PBAs. In this work, MnHCF and TiHCF electrodes were synthetized, cycled with cyclic voltammetry (CV) in different setups and subsequently, the surfaces were characterized with X-ray Ph
